Description
【考案の詳細な説明】
この考案は、先端キャップ内に芯押出機構を装着でき、
軸筒で保管収納したノック式シャープペンシル構造の改
良に関するものである。[Detailed description of the invention] This invention allows a core extrusion mechanism to be installed inside the tip cap.
This relates to an improvement in the structure of a knock-type mechanical pencil that is stored and stored in a barrel.
一般にノック式シャープペンシルにあっては芯押出し機
構は先端キャップと軸筒との間の連結部材を介して装着
されており、その組立構造上先端キャップ、軸筒、連結
部材をそれぞれ分解しながら組込まなければならず組立
工数の増加と加工部品の複雑さを伴い、安価に製作する
には困難を呈していた。Generally, in knock-type mechanical pencils, the lead extrusion mechanism is installed via a connecting member between the tip cap and barrel, and due to its assembly structure, the tip cap, barrel, and connecting member must be disassembled and assembled. This requires an increase in assembly man-hours and the complexity of processed parts, making it difficult to manufacture at a low cost.
この考案の目的は、組立容易で、構造簡単なシャープペ
ンシル特に先端キャップ構造を提供するものである。The purpose of this invention is to provide a mechanical pencil, particularly a tip cap structure, which is easy to assemble and has a simple structure.
以下この考案の実施例を図面第１図、第２図イ。The embodiments of this invention are shown in the drawings Fig. 1 and Fig. 2 A below.
口に基づき説明する。Explain based on word of mouth.
芯底網管１の一部に固定したリードチャック２と、この
リードチャック２に外嵌するチャックリング３及びこの
チャックリング３の軸方向の移動を規制するスリーブ４
と、前記芯底網管１とスリーブ４、内つばとに弾着して
リードチャック２を引込ませる第１のばね５とから成る
芯押出機構を内挿する合成樹脂材の先端キャップ６が先
端芯吐出孔６ａを有し、又他端開口縁６ｂに複数個のＬ
溝の係合孔６Ｃが周設され、外周に固定部６ｄを形成さ
れて構成しである。A reed chuck 2 fixed to a part of the core bottom net pipe 1, a chuck ring 3 fitted onto the reed chuck 2, and a sleeve 4 for restricting movement of the chuck ring 3 in the axial direction.
A tip cap 6 made of a synthetic resin material is inserted into the tip cap 6, which is made of a synthetic resin material and which inserts a lead extrusion mechanism consisting of the core bottom net pipe 1, the sleeve 4, and the first spring 5 that snaps onto the inner brim and retracts the reed chuck 2. It has a discharge hole 6a, and a plurality of L on the other end opening edge 6b.
An engaging hole 6C of a groove is provided around the periphery, and a fixing portion 6d is formed on the outer periphery.
しかも、この係合孔６Ｃに対向する如く外周に保合突起
７ａ、７ａを形成したクッションストッパー７が前記ス
リーブ４端に弾着する筆圧調整のための第２のばね８を
掛止せしめる如く、前記係合孔６ＣのＬ溝内に係止しで
ある。Moreover, the cushion stopper 7, which has retaining protrusions 7a, 7a formed on the outer periphery so as to face the engagement hole 6C, is adapted to engage the second spring 8 for adjusting the writing pressure, which snaps onto the end of the sleeve 4. , and is locked in the L groove of the engagement hole 6C.
一方前記先端キャップ６の外周固定部６ｄには、軸筒９
が先端に内ねじ９ａを形成されて噴込固定できるように
構成されている。On the other hand, the outer peripheral fixing portion 6d of the tip cap 6 has a shaft tube 9.
An internal thread 9a is formed at the tip so that it can be fixed by injection.
尚この固定部６ａと軸筒９との固定は、圧入嵌合にして
もよい。Note that the fixing portion 6a and the shaft tube 9 may be fixed by press-fitting.
更に前記先端キャップ６内の第２のばね８も芯押出機構
上は必要でなく、他のパツキンに置換てもよく、その際
クッションストッパー７はスリーブ４の係止に用いられ
る。Further, the second spring 8 in the tip cap 6 is also not necessary for the core extrusion mechanism, and may be replaced with another gasket, in which case the cushion stopper 7 is used to lock the sleeve 4.
従って、この考案では先端キャップ６内に芯押出機構が
全て挿着できることになり１、組立上、単に軸筒を固定
してやればノック式シャープペンシルとして簡単に製作
できることになる。Therefore, in this invention, the entire lead extrusion mechanism can be inserted into the tip cap 6, and a knock-type mechanical pencil can be easily manufactured by simply fixing the barrel.
又各構成部品も少く、複雑な加工を伴うことなく、安価
に製造でき効果は大なるものである。Moreover, the number of each component is small, and it can be manufactured at low cost without complicated processing, and the effect is great.
